Table Sizes
The C-Series is an industrial 5-axis fixed bridge machining center for processing dense materials, such as solid wood, advanced polymer plastics, composites, and nonferrous metals. Its overall weight, mass, and rigidity deliver fast feed rates, deep per pass cutting, better finishes, longer tool life, and less maintenance over the lifetime of the machine. Available with a wide range of options, let us configure the C-Series 5-Axis to your specific application and get you an edge over the competition.Ā
A unique benefit of the twin table design is that when one table is in the forward position and one is completely back, you can place a part on each table that is the same size as the table and still independently machine completely around both parts. You can also perform pendulum processing or add a second spindle for dual process capability.
With the twin table configuration, you can load Table 1 safely while performing machining operations on Table 2. Then, while the machine switches to processing material on the newly loaded Table 1, you safely remove parts from Table 2 and reload the table. This technique is known as Pendulum Processing, and it keeps your production continuously flowing.
By adding a second spindle to the twin table configuration, you gain flexibility in your production, a value equal to buying an additional machine without the expense or taking up valuable floor space. You can cut twice as many parts in the same time period.Ā
- Use one spindle to machine one process on Table 1, while the other spindle machines an entirely different process on Table 2.
- Use both spindles on an alternating basis to perform different operations on a single workpiece.Ā
- Use both spindles on a fixed center distance to produce identical parts at the same time on the same table (while still pendulum processing) or different tables.
- Use both spindles on a frequently adjusting or varying center distance while working on a single process.
- Park one spindle and electronically lock the tables together, giving full table access to the other spindle for machining large or oversized parts.

Customize the C-Series 5-Axis machine with accessories. Here you’ll find ways to increase your productivity. Select your tool lubrication, eliminate measuring errors with automatic tool measurement systems, and more.

C-AXIS
With a C-Axis (aka 4th axis), you can machine at an angle, including on the sides of your material, to create complex contours (such as helixes), otherwise not possible with a 3-axis machine. This comes standard on a 5-axis machine.

CONTINUOUS C-AXIS
With continuous C-Axis, a 5-axis machine gets unrestricted rotational movement of the C-axis. Without this option, a traditional 5-axis spindle has to unwind itself after a set amount of rotation.

AIR BLAST
Bursts of air keep tools cool and remove debris and chips from the cut without the need for coolant.

ATLM SYSTEM (METROL)
Precisely measures the length of your tool and automatically feeds that value into your CNC machine controls.

ATLM SYSTEM: TS27R (RENISHAW)
Precisely measures the length and diameter of your tool and automatically feeds that value into your CNC machine controls. It also detects if a tool is broken.

ATLM: NC4 (RENISHAW)
Precisely measures the length and diameter of your tool, without contact, and automatically feeds that value into your CNC machine controls. It also detects if a tool is broken. NC4 is application dependent; table constraints may apply.

AUTOMATIC GREASE LUBRICATION
Automatically greases your tools, bearings, and ball screws at regular intervals.

GREASE DRIP PANS
Drip pans (a.k.a. trays) catch excess lubrication that might otherwise cause contamination or other hazards.

VOLUMETRIC LASER COMPENSATION
With volumetric laser compensation, machining tools are automatically calibrated and the machine makes any necessary adjustments.
Note: Depending on your machine, C.R. Onsrud sends out a third-party A2LA-accredited company to your facility to perform volumetric compensation.
Dust management systems connected to appropriate dust collection systems capture chips, dust, and other airborne particles that would otherwise be harmful to humans and the machining environment. We offer dust management systems that are geared toward the materials you’re machining and your production environment.

SERVO HOODā¢
With CR Onsrud’s innovative servo-positioned dust hood, we have improved upon the standard 2-position dust hood and given the CNC machine the ability to automatically adjust the dust hood’s height offset based on tool length, relative to the workpiece. This helps customers, who machine with a variety of tool lengths, get the most effective dust collection regardless of the tool length.

DUST STANCHION KIT
Designed for low ceilings and shop floors with layout constraints, a dust collection stanchion kit transitions dust to your collector from either side of the machine.

AIR KNIFE
Engineered especially for fine or coarse chips (e.g., hard composites, fiber cement, metal, etc.), programmable air knives clear harmful debris from your linear guides.

REAR ENCLOSURE
Partial standalone enclosures provide additional safety when the back of a machine is not against a wall.Ā

FULL ENCLOSURE WITH OR WITHOUT A ROOF
A fully enclosed machine contains debris, reduces noise levels, protects your electronics and mechanical drives from both wet and dry machining, and safely isolates the operator from the machining zone and airborne particles.

MANUAL SLIDING DOORS
These doors are manually controlled by you for access to the machine’s enclosure. For safety purposes, the doors should be closed when the machine is in operation.

AUTOMATIC SLIDING DOORS
These doors are activated and controlled by PMC servo motors. For safety purposes, the machine is placed in a feed hold state if the doors are not properly closed.

ENCLOSURE DUST COLLECTION PORTS
Dust collection ports are integrated with your vacuum system to move dust and debris away from the work area.

CENTER PARTITION
With the partition in place, the machine is split into two separate zones, so you can safely load/unload parts in the unused zone. Pivot the partition against the wall and the machine resumes operation across the entire table.Ā Ā

LASER SAFETY SCANNER
The Onsrud Laser Safety Scanner sets an invisible barrier that triggers your machine’s E-Stop when crossed.

SENSING MATS
Sensing mats sense the pressure of an operator or object on them, alerting the machine to turn off.
Automation systems are typically not integrated with the 5-Axis C-Series (an already highly automated system) except as listed below. If you are looking for material-handling infeed and outfeed systems for panel processing applications, we recommend the T-Series, M-Series, or G-Series. See Automation for more information or contact us. We are happy to discuss options with you.

STANDALONE LABEL PRINTER
This auxiliary equipment can create and affix labels to parts for tracking and identifying parts for use in downstream operations or at the job site.

BARCODE SCANNER
Scan a barcode (machine-readable data) from a document and the machine automatically retrieves the specified program, tooling list, and set-up directions for that job.

ROBOTICS INTEGRATION
Devices are strategically incorporated into your production to automatically perform repetitive tasks, so you and your team can focus on projects that grow your business.
Onsrud Tooling is a direct and easy way to buy high-quality cutting tools at great prices for your Onsrud machine. Choose from:
Ā
Drill Blocks:
Drill Blocks support the simultaneous machining of a set number of holes, evenly spaced with the same or varying diameters. These are not available on a 5-axis machine, but if you’re interested in this capability, see our C-Series 3-Axis machine.
Ā
Aggregates:
Depending on your specific application, the C-Series 5-axis supports 1000’s of specialty tools to perform specialized functions for unique projects. Not all aggregates work with every machine configuration. We recommend discussing your specific application requirements with our team.
Ā
Saw Blades:
Saw Blades attach to a CNC machine to create intricate notches, miter cuts, and straight cuts on up to 5 sides of your material on a 5-axis machine. The saw can also be used as a cutoff tool.
Not sure what you need? Weāve got you covered, our knowledgeable staff is on hand to help with your tooling needs.

AGGREGATE RING
The Aggregate Anti-Rotational Retention Ring mounts to the underside of the spindle, giving it the capability to pick up specialized tooling from the Automatic Tool Changer and preventing the aggregate head from rotating during machining.

90° HEAD
A 90° head gives you the capability to perform lateral machining operations on a 3-axis machine.

DUO 90° HEAD
A Duo 90° head gives you the capability to perform lateral machining operations using different tools in opposite directions on a 3-axis machine.

QUAD 90° HEAD
With a Quad 90° head, youāll easily add lateral machining operations to your 3-axis machine using four tools in each direction.

ADJUSTABLE ANGLE
An adjustable angle head allows you to set the angle at which you want to cut, for up to 5-sided machining on a 3-axis machine.

FLEX ANGLE
With a flex angle head, you can perform horizontal and angular machining operations on a 3-axis machine without having to reposition your workpiece.

MOULDER HEAD
Mill, plane, carve, and bevel, symmetrical and asymmetrical shapes on a 3-axis machine, with the addition of a moulder head aggregate.Ā

OSCILLATING KNIFE
Cut out sharp corners and radii from flexible materials, such as packaging foam, tool foam, plastic, or cardboard with an oscillating knife aggregate.Ā

SMALL DIAMETER SAW BLADE
(up to 6ā³)
The spindle automatically picks up and returns small diameter saw blades (up to 6ā³) from the station that is mounted on the machineās bridge or column.
Note: (Requires a 5-axis machine unless an aggregate is utilized)

DEDICATED AGGREGATE STATION
With a dedicated aggregate station, you can automatically store and retrieve specialty tools (such as saw blades) that are too large or heavy to fit in a standard automatic tool changer.Ā
These devices accurately locate your workpiece in orientation to the table and the tooling. To properly secure your workpieces, it is important to have the correct work-holding device for the material you are cutting. Proper work holding and material positioning ensure precise and efficient machining.

CUSTOM VACUUM ZONES
With custom vacuum zones, you tailor the size and location of vacuum areas for part-holding and can shut off sections of the table to concentrate vacuum to specific zones.

ONSRUD MATRIX GRID TABLE
The Onsrud grid table provides a grid pattern for multiple part-holding options, such as gasketing, vacuum pods, clamps, etc. and is compatible with most third-party products.

CUSTOM / MECHANICAL FIXTURING TABLE
Custom fixturing is adapted to hold irregularly shaped parts or panels that cannot be held by traditional methods.

T-SLOT
The channels of T-Slot tables are used for linear positioning of clamps and vices across the surface of the machine’s table.Ā

LATHE (ROTARY)
With a rotary axis lathe or chuck, your machine operates as a turning center with live tuning. It rotates bar stock and long and skinny components to create chair legs, columns, etc.

REFERENCE (POP-UP) PINS
Reference pins are for quick, reliable, and repeatable placement of your workpieces on your CNC machine.Ā

PROBING
(RENISHAW PROBE)
A part-probing system adjusts the origin of your part prior to machining, performs in-process QC for tight tolerance applications, and performs post-machining QC to approve or reject a part before it is taken out of its work holding.

LASER PATTERN PROJECTION SYSTEM
Without touching the material, a Laser Pattern Projection Alignment System provides true to scale patterns of one or several aligned or nested objects, transferred from CAD software onto the CNC table.
Note: This option is common for high-mix shops and when using vacuum pods.

VISION RECOGNITION (FIDUCIAL)
A fiducial vision recognition system scans for reference points to identify a sheet’s position. The program and tool paths automatically adjust to the position.
Note: This option is common in the signmaking industry where sheets are otherwise difficult to align perfectly.Ā

PENDULUM MODE
TABLE READY & RESUME BUTTONS
Quickly restart (resume) paused programs and prepare (ready) the machine to start immediately after a process is complete.
